　　Growing industrialization and urbanization has put human beings and other living organisms at risk against new threats due to the contamination of food, water and air. These Contaminants endanger all the living organisms in this world, especially for human beings genetic disorders and unknown diseases become common nowadays. The WHO statistics show that more than 422 million people worldwide are suffering from contamination related illness. The growing prevalence of such disorders has been linked to exposure to chemicals in plastic, food and water. Although regulatory steps have been taken to minimize risk, cases of overexposure (2011 Taiwan food crisis, Flint and Hong Kong lead contamination, etc.) still occur. Detection of these chemicals is done in testing labs using expensive and time consuming mass spectrometer systems that require specially trained users. In the regard, we demonstrate a real-time monitoring system for a rapid pre-screening test that could curtail cases of contamination. Over the years, we have developed an electronic sensor platform based on molecular level interaction between the target and analyte to detect these toxins[1] [2]. The advantage of our sensor platform is that it can be used for on-site detection; it is easy to operate and provides results on real-time basis. In addition, we have demonstrated a sensor system to monitor pulse waveform in real-time[3]. This would allow the user to quickly self-diagnose for problems such as myocardial ischemia and seek medical attention immediately. In this talk, I discuss the latest advancements of our sensor platform in terms of basic science to successful launch in the market as an example of “Research to Realization”.
